The presence of Eriogaster catax has been confirmed in 49 locations the province Álava and three within Condado de Treviño Burgos, corresponding to 27 UTM squares 10 x km. This brings total number known for Spain 72, which represent a 53% increase with respect previous knowledge this country. species is widely distributed study area, occupying both supratemperate supramediterranean ecosystem la...

On the Vidlič mountain, mixed mesophilic mountain beech forests (Fagetum submontanum serbicum) have been recorded at altitudes of 700 - 1000 m, following localities: Crni vrh, Vazganica, Kranjci, Planinarski dom, and Visočka Ržana. Phytocenological research was performed on mentioned localities by Braun-Blanquet method (Braun-Blanquet, 1964). It taken 11 phytocenological plots. Beech (Fagus moe...

BACKGROUND In line with the current tendency towards the production of the so-called safe foods, the use of environmentally-friendly methods for the extraction of polyphenols from fruits has been sought. Citric acid is a good solvent in the preparation of phenolic compounds for the food and pharmaceutical industries because it is a natural antioxidant and is non-toxic for the environment. Furth...

Floodplain forests have become rare in Europe due to anthropogenic changes. A critical aspect of their restoration is reintroducing flooding via dike relocation, as implemented at the Elbe River near Lenzen/Germany. How forest development influenced by relocation still unclear and difficult predict. Inside area River, most trees were planted. Due high tree mortality, we asked if relative elevat...

The hawthorns Crataegus azarolus L. and monogyna Jacq are two ecologically medicinally important endemic tree species that occur only in forests of oak the mountain ranges Kurdistan region Iraq (KRI). These have been degrading across at an alarming pace due to climate-related factors (e.g., wildfire events drought) anthropogenic drivers. Nevertheless, there is a gap understanding their distribu...

Tree seedling flooding tolerance for 22 species was assessed under controlled field condi­ tions. Initial heights under control (freely draining soil, n = 20 per species) and flooded (stand­ ing water, depth = 10 cm, n = 20 per species) conditions were measured in March 1990. Sur­ vival, height and diameter growth were determined after 120 days. Recovery from flooding effects was assessed in th...

Crataegus oxyacantha is an important herbal supplement and famous for its antioxidant potential. The antioxidant in combination with anticholinesterase activity can be considered as an important target in the management of Alzheimer's disease. The compounds isolated from C. oxyacantha were evaluated for cholinesterases inhibitory activity using Ellman's assay with Galantamine as standard drug. ...

Abstract Crataegus species (Rosaceae) or hawthorns form dense thickets and displace native vegetation out of their range. In South Africa, monogyna C. mexicana are under surveillance but there is lack information on pollination ecology. Therefore, this study sought to investigate the mechanism potential insect pollinators these plants. Pollinator exclusion experiments were conducted ten plants ...
